It was eventually revealed that the turban was used to hide the face of Lord Voldemort on the back of Quirrell's head, as he was possessing Quirrell at the time. It is therefore unlikely that Quirrell's story about the Zombie was true, and the fact that the native range of zombies is South America makes the veracity of the tale regarding the African prince even more dubious.

The wizarding travel agency TerrorTours offers trips along the Zombie Trail, where hikers could "experience the thrill of coming face to face with the living dead."[2]

Behind the scenes

It is possible Zombies may be related in some way to Inferi, or may even be the same thing, although this is unconfirmed. However, Pottermore makes Zombies sound more like a naturally formed creature, as they are given a native range.
